至少 40 年来，人们知道通过海洋落下的颗粒有机物质雨的存在，并构成海底生物的食物来源（Honjo 1990，1996）。颗粒物质从表面沉入更深的水域和海底是海洋内碳和其他生物元素运输的主要途径之一，并且各种生物、物理和化学过程在颗粒下沉时改变其有机和无机成分。在过去的四十年中，海洋地球化学家对海洋中颗粒有机物的沉降有了很多了解，但仍然存在许多问题。本章回顾了关于海洋中下沉颗粒有机物的数量和质量的知识，描述了其随时间和空间的变化，并考虑了几个尚未解答的更大问题。
For at least 40 years, the rain of particulate organic matter falling through the ocean has been known to exist and to constitute a source of food for organisms on the sea floor (Honjo 1990, 1996). Sinking of particulate material from the surface to deeper waters and the sea floor is one of the major pathways for the transport of carbon and other bioelements within the ocean, and a variety of biological, physical and chemical processes alter the organic and inorganic composition of particles as they sink. In the past four decades, marine geochemists have learned much about sinking particulate organic matter in the sea, yet many questions rema1n. This chapter reviews what is known about the quantity and quality of sinking part1culate organic matter in the sea, describes how it varies in time and space, and considers several larger questions yet to be answered.
